A severe failure of equilibrium thinking. The gov‘t wants to reduce admin burdens and bureaucratic rules - ok. For this to work, you need trust in the principles that are governed by the rules. The first rule that they cut is - the freedom of information act. So now they can do what they want.

Discussing the work of Adam Smith and capitalist economic systems with students in my Intro Micro class and came across this banger in The Theory of Moral Sentiments (1759): "This disposition to admire, and almost to worship, the rich and the powerful, and to despise, or, at least,...

FT: Donald Trump declared making more than 22,000 stock transactions 😳 in 2025, according to the FT analysis. His immediate predecessor, Joe Biden, made 13 transactions over four years. In his first term, Trump made 517. www.ft.com/content/9067...

Things ain't black or white. Most of today's agreements likely help the country, which is great. But the gov't also agreed to curtail 🇩🇪's freedom of information act, in a way that helps only very few people - the members of gov't. bsky.app/profile/arne...

German scholars act against those who would repeat historic mistakes. Good.

👇🏼 on creating heat that harms everyone, but for own benefit. Luckily, only one of 🇪🇺, 🇺🇸, 🇨🇳 does it.

8) Double down on net zero, but as economic policy not climate policy. Stop talking about net zero and start talking about electrification. UK was fast to digital tech where others clung to fax machines; now it is fast to electric industry where others cling to clunky old fossil fuels. Own it.

🇪🇺's Emmissions Trading System is a key item for everything, making the discussion of upcoming changes so important. 👇🏼

A strange thing, the expansion of electrification: it will come sooner or later, but it is VERY important that it comes sooner.

Ironic that the Autobahn is the first to melt

US & friends ask 🇪🇺 to turn up the heat a bit more www.energy.gov/articles/us-...

Thank you! We discuss how partial altruism can create acrinomy in voting equilibrium. Members of two groups (G,C) consume a dirty good and and vote for a carbon tax. G's members pollute less as they care about other members of G. That's great but it also pulls G and C apart in the tax voting game.

„Often overloooked, heat already kills more people in the U.S. annually than any other extreme weather event.“

„We prohibit the prohibition of artificial intelligence.“ One of the more German sentences 😄 and an empty threat, I dare say. www.br.de/nachrichten/...

The German pensions reform commission (experts and politicians) has made its proposals — if the government agrees to implement them fast, their crisis may be over for now. Some criticism arose already 👇🏼 but it is mild overall. First reports appear to make it likely that they see it through.

Taking the big picture, like the IMF does

Why newly enfranchised women voted against the parties that secured their rights: We reveal that religious "identity payoffs" outweighed material self-interest, proving that cultural identities can decouple political choice from economic incentives even when stakes are high.

Old question: Do we need game theory? Old answer: yes, to study economic competition etc. Perhaps more convincing: yes, to study language. Today's discussion of AI-generated speech 👇🏻 is just an example. 1/4

Actually, no need to hide behind an energy crisis 👇🏼 as it is unconditionally best to *renew and electrify*. (Best for the for the planet and the economy. Hopefully the minister understands that this comes from analysis, not ideology.)

The 🇩🇪 minister for digital transformation has now indicated that he may soon propose a guideline for AI use in gov't affairs. Good. For politicians' speeches, the guidelines should recognize that a text carries meaning not by itself.

🇩🇪 politicians' AI-generated speeches are interesting because (a) the problem may generalize, and (b) they reveal much about the speaker's intentions. I wrote about it in today's FAZ, from a perspective of game theory / pragmatics / speech acts. #langsky #econsky 1/n www.faz.net/aktuell/feui...
